Compare any two graphics cards:
Radeon HD 5550 vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 5550 has a clock speed of 550 MHz and a DDR2 memory speed of 400 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is made up of 320(64x5) SPUs, 16 TAUs, and 8 ROPs.Compare all that to the Radeon HD 6570 (OEM) 1GB, which comes with core clock speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 6570 (OEM) 1GB should in theory be a lot superior to the Radeon HD 5550 in general. (explain)
Texel RateThe Radeon HD 6570 (OEM) 1GB should be much (more or less 77%) more effective at AF than the Radeon HD 5550. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 6570 (OEM) 1GB is a better choice, though not by far. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
